PURPOSE: This study examined the effects of the craniovertebral angle, proprioception (joint error test), and the upper trapezius on the muscle tone when comparing cervical stabilization and scapula stabilization exercises and when two exercises were performed together. METHODS: The participants in this study agreed in advance, and this study was carried out by recruiting 27 university students in their twenties with mild frontal posture. The subjects were assigned randomly to three groups that performed cervical stabilization exercises, scapular stabilization exercises, and both cervical and scapular stabilization exercises. One-way repeated ANOVA was used to analyze the evaluation values of the 1^st, 3^rd, and 6^th weeks of exercise intervention within the group, and one-way ANOVA was used to compare the difference in the effects of exercise intervention among the three groups. RESULTS: Proprioception was significantly different in the cervical stabilization exercises (CSE) group and the cervical stabilization exercises + Scapular stabilization exercises (CSE+SSE) groups at three weeks, and there was a significant difference between the scapular stabilization exercises (SSE) group and the CSE+SSE group (p < .05). At six weeks, there was a significant difference between the CSE group and the CSE+SSE group, and there was a significant difference between the SSE group and the CSE+SSE group (p < .05). There was a significant difference between three and six weeks in the CSE group (p < .05). In the SSE group, there was a significant difference between pre and six weeks, and between three and six weeks (p < .05). In the CSE+SSE group, there was a significant difference between pre and three weeks, and between pre and six weeks (p < .05). On the other hand, there were no significant differences between CVA and muscular tone in all three groups (P > .05). CONCLUSION: In all groups, the proprioception (joint error test) showed significant improvement, and the CSE+SSE group showed greater improvement than the other groups. As a result, the appropriate combination of neck stabilization exercise and scapular stabilization exercise effectively improved proprioception in the presence of forward head posture (FHP).

Background: Shoulder stabilization commonly involves two components: the glenohumeral stabilization exercise (GSE) and scapular stabilization exercise (SSE). Despite the fact that the shoulder stabilization has advantageous merit, to our knowledge, only a few studies have compared the superior of the GSE and the SSE. Objects: The purpose of this study was to assess the effects of GSE in patients with nonspecific shoulder pain. Methods: Thirty subjects with nonspecific shoulder pain were randomly divided into an experimental group and control group, each with 15 patients. The experimental group used an GSE, whereas the control group did SSE. All subjects were measured in shoulder stability, scapular symmetric alignment, pain, muscle power, and range of motion before and after the intervention. Results: GSE resulted in significantly better shoulder stability (p=.046, from $8.67{\pm}7.54$ score to $13.93{\pm}9.40$) in the experimental group compared with SSE in the control group. However, no significant effects were observed for scapular symmetric alignment including the angles of inferior scapular distance (p=.829) and inferior scapular height difference (p=.735), pain (p=.113), muscle power including shoulder flexion (p=.723) and abduction (p=.897) and range of motion including shoulder flexion (p=.853) and abduction (p=.472). Conclusion: These findings suggest that GSE may be more effective in increasing the shoulder stability than the SSE in patients with nonspecific shoulder pain, probably through a centralization effect on the shoulder mechanism.

Purpose : Scapular dyskinesis, it have been shown to be common in overhead athletes and has been associated with RC muscle strength. Posterior shoulder tightness (PST) has been suggested as an important factor causing scapular dyskinesis. Therefore, rehabilitation programs should focus on a posterior shoulder stretch combined with scapular stabilization exercise (PSSE) intervention. Determine the effects of posterior shoulder stretch combined with scapular stabilization exercise on the rotator cuff (RC) muscles strength, functional strength ratio (FSR), range of motion (ROM), and pain. Methods : 30 adolescent baseball players participated and subjects were allocated PSSE group (n=15) or the SSE group (n=15). Both group performed a 6-weeks intervention and measured of isokinetic peak torque/body weight (PT/BW) of concentric external rotator (CER), eccentric external rotator (EER), concentric internal rotator (CIR), eccentric internal rotator (EIR), FSR, ROM, and pain. Results : After 6 weeks PSSE, significant increase CER PT/BW (+6.02±4.76 %), EER PT/BW (+5.39±4.22 %), EER to CIR ratio (+.17±.16), and internal rotation ROM (+15.08±3.57 °). Whereas, significant decrease EIR to CER ratio (-.14±.18), external rotation ROM (-12.00±6.94 °), and GIRD (-17.41±2.84 °) compared with pre-intervention. No significant difference of isokinetic PT/BW of CIR and EER post-intervention. In the SSE group showed no significant difference all measurements for isokinetic PT/BW, FSR, and ROM post-intervention. The pain was significant improve both PSSE group (-3.25±1.60) and SSE group (-2.83±1.85) post-intervention. Conclusion : Both the PSSE and SSE interventions led to more pain relief. However, only the PSSE group showed ROM, CER, EER PT/BW, and FSR improvements. These results might suggest that the PSSE intervention is a more effective program for improving RC muscle strength and balance, in particular, concentric and eccentric ER muscle strength, FSR and can expect to prevent shoulder injuries in adolescent baseball players with scapular dyskinesis.

PURPOSE: This study examined the effects of an exercise program for the thoracic spine and scapula rather than the neck, which is the primary site of pain. METHODS: Thirty-two elementary school teachers with a forward head posture (FHP) were assigned randomly to either the experimental group (n = 16) or the control group (n = 16). The experimental group performed scapular stabilization exercise (SSE) and thoracic extension exercise (TEE), and the control group performed cervical self-myofascial release exercise and stretching exercise. The pulmonary functions, pain, craniovertebral angle (CVA), and cervical range of motion (CROM) were measured before the intervention and six weeks after. RESULTS: The within-group comparisons showed that the VAS and CROM (except for extension) in both groups were significantly different before and after the intervention (p < .05). The changes in the maximum inspiratory pressure (MIP), maximum expiratory pressure (MEP), forced vital capacity (FVC), forced expiratory volume at 1 sec (FEV1), and CVA were significant only in the experimental group (p < .05). The between-group comparisons showed a significant difference in the FVC, FEV1, VAS, CVA, and left lateral flexion (p < .05). CONCLUSION: The combination of SSE and TEE in the experimental group was more effective in improving the FHP and breathing ability. Moreover, the experimental group and control combination appeared to be effective in reducing pain and improving the CROM. The combination of SSE and TEE, which are exercises that do not target the cervical spine directly, was effective in improving the posture, respiration, neck pain, and CROM in elementary school teachers with FHP.
